  For the moment I've had to create several backup jobs instead of one big backup it's e.g. servers01-06, 07-12, 13-18. Which isn't ideal as it's harder to manage, but is what it is!

  Hard to say from just a screenshot. What version of XO are you running? How long did you wait for the logs to load? Did you try refreshing the page? FWIW, I've noticed that XO seems to take longer to load this page than it did previously. P.S. Technically, you aren't running XOA (the pre-built XO appliance).

  Same answer as the other topic, as I exactly said in my previous post here: you can solve this in XO, Dashboard/health view.

  I've been spending some time on it for the last few nights, and my skills are improving little by little. I think Ubuntu desktop was the closest I got to functional, there is a custom image for the Rpi3b+ that I found and it was one of the attempts that got to trying to start the XO-server service and failed. I was never able to get the xo-server to start manually either and the log files didn't give me anything I understood. One of the versions that worked the least was CentOS 7 for RPi, node.js is not available for it in the normal repos. I have more experience with CentOS from a few years ago and more comfortable with it, may have to look into compiling all the dependencies from source to see if I can make it work. I think an RPi 4b with 2gb or 4gb of RAM might be a better choice, but I have the 3b+.

  It's simple, you can't for now. It's the management network only. What you can do, is to add a network to XO that will be inside the network you want, so at least the link between XO and the storage/backup will be the one you want.

  This guide shows an old UI of XO, but you can always set the HA for the VM in its Advanced Tab. HA at the pool level might be enabled using the command displayed in the blog post. So far enabling HA on the pool level isn't exposed in XO because HA is causing more issues than it solves in general. If you decide to enable it on the CLI, it means that you probably understand what you do. If you don't know where to find a SR UUID, using HA might expose you to VERY bad experience. BTW, you can find it in SR view, click on the SR you want to use as HA SR, you'll see the UUID just beneath the name. As someone said in this forum few weeks ago: Everybody wants HA but not everyone needs it

  Also please note that's not a guarantee to boot the VM on this host. In fact, there's no way to be 100% sure it will. It's just than now XCP-ng will do its best to honor this. But eg, if there's not enough RAM on the host, then it will boot on another host of the pool.

  I think, solution you are looking for is direct disk access. It's possible. I use it for my file server VM (FreeNAS) with five 4TB wd red drives (zfs). Passthrough entire PCI storage card is better, but even cheap server motherboards have 6 sata channels (one for dom0 ssd, and five for file server storage). This is my example (and my UUIDs) mkdir /srv/direct-sata_sr xe sr-create name-label=”Direct SATA SR” name-description=”SATA links to passthrough direct to VMs” type=udev content-type=disk device-config:location=/srv/direct-sata_sr New UUID generated on sr creation ba9b124c-c5ac-2c0b-7b1f-014d9cezzzzz ln -s /dev/disk/by-id/<disk id> /srv/direct-sata_sr/<disk id> ln -s /dev/disk/by-id/ata-WDC_WD5000BEVT-26A0RT0_WD-WXE1A10V7603 /srv/direct-sata_sr/ata-WDC_WD5000BEVT-26A0RT0_WD-WXE1A10V7603 xe sr-scan uuid=ba9b124c-c5ac-2c0b-7b1f-014d9cezzzzz xe vdi-list sr-uuid=ba9b124c-c5ac-2c0b-7b1f-014d9cezzzzz Good luck.

  @olivierlambert I have assigned 1.9TiB to a VM and XOA is saying the VM is using 1.07TiB, but df -h on the VM is saying that I'm using 418GB. So according to XOA I should have about 800GiB left but according to my VM I should have 1.4TB left, there's a pretty big 600GB difference here.

  With iSCSI-HA you just need an IP address that is always reachable from every node. We use the IP address of a managed switch for that. No XCP-ng, no VMs, just a reachable IP address.

  I actually like the current implementation. I am currently using this setup to allow an admin user to have 2 accounts managed by one authentication back-end. One account is a typical self-service user to consume resources according to ACL/Self-service rule sets The other account is used to manage Admin features like backups and XO settings (environment with multiple admins who also consume resources from a shared pool with other departments/teams) I use separate accounts so when admin users create VMs it can go to the appropriate self-service container. I hope any fixes to address the above concern doesn't completely remote this capability or at least adds another method of achieving this.
